Week 8 - Challenge 4 - Bumper

BUMPER DESIGN

AIM:

To design the bumper as for the design consideration from the given class A surface.

OBJECTIVE:

• To design Bumper as per automotive industry Standard.
• Create tooling axis for the given CLASS-A surface.
• Create B Class and C Class surfaces
• Create final surface model and convert it into solid body using close surface command in the part design workbench.
• Perform draft analysis for both Class-A surface and Final part body.

CLASS A SURFACE:

Skin data would be provided to us by the styling team. Class-A surface means visible surface. It gives the aesthetic of the component which is created by the styling team and gives to the part design engineer to create the part with all engineering aspects.

TOOLING AXIS:

Tooling axis represents the opening and closing of the mold core and cavity during the manufacturing of the components. A plastic product designer should consider the best tooling direction to cutdown the cost of the component very less.

DRAFT ANALYSIS OF CLASS A SURFACE:

The Draft Analysis is a command enables you to detect if the part you drafted will be easily removed. This type of analysis is performed based on colour ranges identifying zones on the analysed element where the deviation from the draft direction at any point, corresponds to specified values.

Draft analysis is done after determining the tooling axis, draft analysis is used to check whether the minimum draft (3 degrees) is maintained or not.

CLASS B SURFACE:

Class-B surface means thickness of a part it is not visible and is inside part. In other words, Class-B surface is a surface below a certain thickness from the class-A surface. This is the surface that contains engineering aspects of a model.

CLASS C SURFACE:

Surface that joins class-A and class-B surfaces is class-C surface. Class C is often specified for interior surfaces not readily visible, surfaces that will be covered by another part when assembled.

FINAL PART:

Finally we join class A surface with class C surface. And than the joined part trimed by the class B surface, after we get final closed part. than it will check by using of boundary command.

Here, we create the solid component from the closed surface.

FINAL PART DRAFTING ANALYSIS:

CONCLUSION:

I have successfully created the class-B and Class-C surfaces of Bumper using the given Class-A surface along with the tooling axis in the CATIA surface workbench.
